Gets or sets a value that indicates whether the message is to be persisted to the database immediately, instead of being
held in memory for a short time. This property is ignored if the message is sent to a non-express queue or topic.

Gets or sets the message’s time to live value. This is the duration after which the message expires, starting from when the message is sent to the Service Bus. Messages older than their TimeToLive value will expire and no longer be retained in the message store. Subscribers will be unable to receive expired messages.TimeToLive is the maximum lifetime that a message can receive, but its value cannot exceed the entity specified the
DefaultMessageTimeToLive value on the destination queue or subscription. If a lower TimeToLive value is specified, it will be applied to the individual message. However, a larger value specified on the message will be overridden by the entity’s DefaultMessageTimeToLive value.

Explicit Interface Implementations

This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return null (Nothing
in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the XmlSchemaProviderAttribute to the class.
